Values are presented as median (range). ^#Denotes 0.05 < 𝑃 < 0.10 and *denotes 𝑃 < 0.05 in paired test. HIF-1α: hypoxia inducible factor-1α; HO-1: heme oxygenase-1; HSP72: heat shock protein 72; IGF-1Ea: insulin-like growth factor-1Ea; IL-6: interleukin-6; PGC-1α: peroxisome proliferator activated receptor gamma coactivator 1α.
